<Application Storage Unit 121>

The application storage unit 121 is a storage area that storesapplications sold by the application sales management system 1000. Anapplication traded in the application sales management system 1000 is anapplication operated by the edge server 200. The application storageunit 121 illustrated in FIG. 3 stores an application name, target modelinformation, input information, an application description, anapplication itself, price information, a mall ID, and the like incorrelation with an application ID. The application ID is identificationinformation for identifying an application. The target model informationis model information of the edge device 300 which is an input/outputtarget of the application and is a model name of a CNC machine tool, anindustrial apparatus, an industrial robot, or the like, for example. Theinput information is edge device information including input datainformation or the like input from the edge device 300. The applicationdescription includes a description on a license as a description on thespecifications of an application. The description on a license includesinformation on designation of the edge device 300 indicating whether theedge device 300 that uses the application is designated and informationon the number of edge devices to be used concurrently indicating whetherit is necessary to purchase a number of edge devices 300 to be usedconcurrently or there is no limit in the number of edge devices to beused concurrently, for example. With regard to the use of application,the description also includes a description on renewal of a contract.The price information is information on a sales price of an application.The price information corresponds to a user level of a user who accessesvia the terminal 400 and has price information corresponding to eachuser level. The user level will be described later. The mall IDindicates that the application corresponds to a predetermined mall. Whenan application does not correspond to a mall, the mall ID is blank. Adetailed description of a mall unique to the present invention will beprovided later.

<User Storage Unit 122>

The user storage unit 122 is a storage area that stores information on auser who is authorized to access the application sales management system1000. As described above, in order to access the application salesmanagement system 1000, it is necessary to satisfy predeterminedrequirements (qualifications or the like), and a user who satisfies thepredetermined requirements (qualifications or the like) is assigned witha user ID for accessing the application sales management system 1000.Here, a user includes an end user and an intermediary dealer including aspecialized dealer such as a system integrator and a machine toolmanufacturer.

The user storage unit 122 illustrated in FIG. 3 stores a user name, auser level, an ordering right, edge server information, and the like incorrelation with the user ID. Moreover, the user storage unit 122 maystore a mall ID of a mall that the user is authorized to access incorrelation with the user ID. The user ID is identification informationfor identifying a user. The user level is determined by an attribute ofthe user. In the present embodiment, it is assumed that the user levelhas three levels from user level 1 (also referred to as “ch1”) to userlevel 3 (also referred to as “ch3”). More specifically, user level 1(ch1) indicating that the user is an end user, user level 2 (ch2)indicating the user is a specialized dealer (an intermediary dealer)including a vendor, a system integrator, and the like, for example, anduser level 3 (ch3) indicating that the user is a specialized dealer (anintermediary dealer) including a machine tool manufacturer, a facilitymanufacturer, and the like, for example, are illustrated. In thefollowing description, user level 2 will be also referred to as a lowerintermediary dealer and user level 3 will be also referred to as ahigher intermediary dealer. The ordering right is information foridentifying whether a user (a specialized dealer (an intermediarydealer) or an end user) identified by the user ID is authorized totransmit an application purchase request directly to the applicationsales management system 1000. Only when a user has the ordering right,the user can transmit an application purchase request directly to theapplication sales management system 1000. The edge server information isinformation on the edge server 200 provided in a plant or amanufacturing site associated with the user particularly when the useris an end user and is information for identifying the edge server 200which is an application distribution destination. The edge serverinformation includes at least an edge server ID for identifying the edgeserver 200, address information on a communication network such as an IPaddress of the edge server 200, and the like. The edge server ID isnecessary for identifying respective edge servers 200 when one or moreedge servers 200 are provided in a plant or the like associated with theuser, for example. Moreover, the edge server information may includeinformation on an edge device 300 serving as a client candidate of theedge server 200, which is likely to input and output information withrespect to the edge server 200. The information on the edge device 300may include an edge device ID for identifying the edge device 300, amodel name of the edge device 300, an address (for example, an IPaddress) on a communication network of the edge device 300, and thelike.

<Mall Storage Unit 123>

The mall storage unit 123 is a storage area that stores information on amall. Prior to description of the mall storage unit 123, a mall will bedescribed. FIG. 4 is a schematic diagram for describing a mall of thesales management server system 100 according to the present embodiment.Here, a mall is a virtual store (a mall) which is virtually provided inthe sales management server system 100 and which sells an applicationgroup including one or more applications among applications developed bya specialized dealer such as a machine tool manufacturer, for example. Amall is a component unique to B2B since the present invention isdirected to B2B. The mall is correlated with an application groupincluding one or more applications among applications sold in the mallonly. Predetermined users only can access the mall.

An application 170 illustrated in FIG. 4 illustrates a portion ofapplications stored in the application storage unit 121 of the salesmanagement server system 100. The application 170 includes a generalapplication 171 and an exclusive application 172 (also referred to as a“mall application”). The general application 171 is an application whichcan be loaded into the edge server 200 by any end user having a user IDand which can be accessed in the sales management server system 100(which is not included in any mall). Moreover, the exclusive application172 is an application which is included in a predetermined mall andwhich can be loaded by a specific user only who is authorized to accessthe mall. The exclusive application 172 can be accessed in the salesmanagement server system 100 by a user only who is authorized to accessthe mall. The exclusive application 172 is an application which has beencreated and/or is being developed by a higher intermediary dealer suchas a machine tool manufacturer, for example. A user (that is, a user whois authorized to access a predetermined mall) who is authorized tobrowse, purchase, or distribute exclusive applications 172 correlatedwith the predetermined mall may be set uniquely by a higher intermediarydealer (an administrator thereof) such as a machine tool manufacturercorrelated with each of exclusive malls 173 (exclusive malls 173 a to173 c illustrated in FIG. 4). By doing so, it is possible to secureconfidentiality such that users, even an operating company, other than auser who is authorized to access a mall cannot access the exclusiveapplication 172 correlated with the mall (that is, cannot even browseapplications included in the mall). For example, it is particularlyeffective in making the specification of applications in developmentconfidential to users other than a specific user.

In the example illustrated in FIG. 4, user A is given an authorizationto access the exclusive mall 173 a and can browse the exclusiveapplication 172 included in the exclusive mall 173 in addition to thegeneral application 171. Moreover, user B is given an authorization toaccess the exclusive mall 173 a and the exclusive mall 173 b and canbrowse the exclusive application 172 included in the exclusive malls 173a and 173 b in addition to the general application 171. On the otherhand, user C is not authorized to access the exclusive mall 173 and canbrowse the general application 171 only. User D is given anauthorization to access the exclusive mall 173 c and can browse theexclusive application 172 included in the exclusive mall 173 c inaddition to the general application 171. Here, a correlation between theexclusive mall 173 including the exclusive application 172 and a higherintermediary dealer such as a machine tool manufacturer is set inadvance and is stored in the mall storage unit 123.

By providing the application sales management system 1000 with agrouping function using such a mall, an higher intermediary dealer canprovide applications developed by itself (or applications indevelopment) to only end users who are customers thereof for browsing orsales purposes. Moreover, the higher intermediary dealer may not be alsoknown to an operating company since the higher intermediary dealermanages applications included in the exclusive mall 173. Furthermore,since each user can access (browse, purchase, or distribute) theexclusive application 172 only included in the exclusive mall 173correlated with the user ID thereof, each user has no way to know thepresence of the exclusive application 172 included in the exclusive mall173 which is not correlated with the user ID thereof.

As described above, the mall storage unit 123 stores the name of a mall,an administrator ID for identifying an administrator (for example, anadministrator of the mall in the higher intermediary dealer such as amachine tool manufacturer), and an authorized user ID or the like foridentifying a user who is authorized to access the mall, which is set bythe administrator of the mall in correlation with a predetermined mallID for identifying the mall. Moreover, the mall storage unit 123 maystore a description on an application group included in the mall and/oran application ID for identifying applications included in the mall, thenumber of applications, and the like in correlation with the mall ID.

[Modification]

In this embodiment, although the exclusive application 172 included inthe exclusive mall 173 has been described, an application to whichaccess is restricted is not limited thereto. For example, anadministrator ID and an authorized user ID may be set for eachapplication so that an access restriction may be applied to theserespective applications. More specifically, by adding the items of anadministrator ID and an authorized user ID, for example, to theapplication storage unit 121, it is possible to secure confidentialityof the application to persons other than an administrator and anauthorized user similarly to the exclusive mall 173.

<Distribution Management Storage Unit 124>

The distribution management storage unit 124 is a storage area thatstores information on an application distributed to an arbitrary edgeserver 200 in correlation with a distribution destination edge server200. The distribution management storage unit 124 illustrated in FIG. 3stores the distributed application and the distribution destination edgeserver 200 in correlation. The distribution management storage unit 124stores a distribution management record in which an edge server ID foridentifying the distribution destination edge server 200 and anapplication ID for identifying a distributed application are used asretrieval keys and data including an edge server ID of the distributiondestination edge server 200 and an application ID of the distributedapplication is used as a retrieval key (a composite key). In addition tothe retrieval keys, the distribution management record stores data formanaging a distributed application such as a serial number (a licensekey) of the distributed application, a license, a purchase date, adistribution date, a next contract renewal date, a next contract renewalnotification date, a next contract renewal notification destinationaddress, and a notification completion flag.

The serial number (a license key) is a serial number corresponding to apurchased application. The license is information on the edge device 300which is authorized to perform connection and/or input/output to theapplication in relation to the license of an application distributed tothe edge server 200. The purchase date is the date on which a serialnumber of the application is notified of. The distribution date is thedate on which the application is distributed to the edge server 200. Thenext contract renewal date is the next contract scheduled date when thepresent license contract is continuously maintained. The next contractrenewal notification date is a candidate date on which a confirmationnotification whether the present license contract is continuouslymaintained is transmitted to a specialized dealer (an intermediarydealer) who is a purchaser of the application and/or a licensedestination end user of the application. The next contract renewalnotification destination address is the address of the terminal 400 of aspecialized dealer (an intermediary dealer) who is a purchaser of theapplication and/or a license destination end user of the applicationand/or an email address of a specialized dealer (an intermediary dealer)who is a purchaser of the application and/or a license destination enduser of the application. The notification completion flag is a flagindicating whether a confirmation notification on whether a presentlicense contract is continuously maintained or not is transmitted to aspecialized dealer (an intermediary dealer) who is a purchaser of theapplication and/or the license destination end user of the application,and when the notification is transmitted, the flag is set to ON, forexample, in order to indicate that a notification has been transmitted.

By doing so, users can easily retrieve information on the edge server200 to which each application has been distributed and when the contractof the application is to be renewed in the edge server 200. Moreover,users can easily retrieve information on which application and when thecontract of the application is renewed among applications distributed toeach of the edge servers 200. Furthermore, a confirmation notificationof the renewal of the contract of an application can be transmitted tothe next contract notification destination address (for example, theterminal 400 and/or the email address or the like) on the next contractrenewal notification date previous to the next contract update date foreach application and/or each edge server 200. Next, the respectivefunctional units of the control unit 110 illustrated in FIG. 2 will bedescribed.

<Browsing Information Providing Unit 111>

The browsing information providing unit 111 has functions correspondingto an application product information providing unit and a sales priceinformation providing unit. More specifically, the browsing informationproviding unit 111 provides application information (application productinformation) that an end user or a specialized dealer (an intermediarydealer) can browse in response to a browse request for applicationinformation (application product information) from the end user or thespecialized dealer (an intermediary dealer) or the like, received fromthe terminal 400. The browsing information providing unit 111 mayextract application product information on an application (the generalapplication 171) provided to all logged-in users by referring to theapplication storage unit 121 and provide the application productinformation to the terminal 400.

[Browsing of Mall Application]

A case in which an authorization to access a predetermined mall is setto a logged-in user will be described. In this case, first, the browsinginformation providing unit 111 may provide mall information in which anaccess authorization is set to a logged-in user to the terminal 400 in alist form. More specifically, the browsing information providing unit111 acquires a mall ID in which an access authorization is set to theuser by referring to the mall storage unit 123. The browsing informationproviding unit 111 acquires a mall name, an administrator name of themall, and the number of applications included in the mall from the mallstorage unit 123 on the basis of the acquired mall ID and provides themall information to the terminal 400 in a list form on the basis of theacquired data. The browsing information providing unit 111 may provideinformation on the exclusive application 172 included in an applicationgroup correlated with a mall selected via the terminal 400 in a listform. More specifically, the browsing information providing unit 111 mayextract application product information of the exclusive application 172by referring to the application storage unit 121 and provide theapplication product information to the terminal 400.

As another processing method for providing the application productinformation of the exclusive application 172 correlated with the mall,first, the browsing information providing unit 111 may specify a mall IDincluding an authorized user ID and an administrator ID on the basis ofthe user ID included in a received browse request by referring to themall storage unit 123. When the mall ID is specified, the browsinginformation providing unit 111 may extract the application productinformation of the exclusive application 172 correlated with thespecified mall ID by referring to the application storage unit 121 andprovide the application product information to the terminal 400. In thismanner, when an authorization to access a predetermined mall is set to alogged-in user, the browsing information providing unit 111 may providefirst the mall information in which an access authorization is set tothe user and then provide the information on the general application171. The browsing information providing unit 111 may provide the generalapplication 171 and the exclusive application 172 which is a mallapplication simultaneously.

[Browsing of Price Information]

The browsing information providing unit 111 provide price informationcorresponding to a user level set in advance to an end user or aspecialized dealer (an intermediary dealer) in response to an inquiry orbrowsing of price information (application sales price information) ofan application from the end user or the specialized dealer (anintermediary dealer), received from the terminal 400. Specifically, enduser price information only is provided to the end user whereas end userprice information and wholesale price information for the specializeddealer (an intermediary dealer) are provided to the specialized dealer(an intermediary dealer) or the like. Due to this, the browsinginformation providing unit 111 checks the user level of a usercorresponding to the user ID included in the received browse request byreferring to the user storage unit 122.

Here, the user level and the provided price information will bedescribed. FIG. 5 is a diagram illustrating an example of acorrespondence table 150 between a user level and price informationaccording to the present embodiment. When the user of the terminal 400is an end user, the browsing information providing unit 111 extracts theprice information corresponding to ch1 as browsable price information.When the user of the terminal 400 is a lower intermediary dealer, thebrowsing information providing unit 111 extracts the price informationcorresponding to ch2 as browsable price information. When the user ofthe terminal 400 is a higher intermediary dealer, the browsinginformation providing unit 111 extracts the price informationcorresponding to ch3 as browsable price information. Here, when the userof the terminal 400 is a lower intermediary dealer or a higherintermediary dealer, as illustrated in the correspondence table 150, theprice information corresponding to ch1 as well as the price informationcorresponding to the level thereof are extracted. The browsinginformation providing unit 111 generates a browsing screen 160 includingthe extracted application information and the price information of theapplication corresponding to the user level and provides the browsingscreen 160 to the terminal 400. When a plurality of applications isextracted, the browsing information providing unit 111 may generate anapplication list screen and transmit the application list screen to theterminal 400. When a selection associated with one application isreceived from the terminal 400, the browsing information providing unit111 may extract information on the selected application from theapplication storage unit 121 and generate the browsing screen 160.

FIG. 6 is a diagram illustrating an example of a browsing screendisplayed on a terminal according to the present embodiment. Thebrowsing screen 160 includes an application description 165 and adescription 166 related to an application license, for example. Thedescription 166 includes extracted price information 161, a licensequantity 162, license description information 163, an edge server IDindicating portion 164 and provides these pieces of informationcollectively as information on a license. Since the browsing screen 160includes the license description 166, each user can check information ona necessary license. The license quantity 162 is provided optionally.Here, FIG. 6 is an example displayed on the terminal 400 when the useris a higher intermediary dealer who has an ordering right. Therefore,the price information 161 indicates an end user price 161 acorresponding to user level 1 (ch1) and a higher intermediary dealerprice 161 b corresponding to user level 3 (ch3). Moreover, the browsingscreen 160 also serves as an ordering screen and displays the licensequantity 162 and the edge server ID indicating portion 164 so thatordering can be realized. When the user is an end user who does not havean ordering right, the description 166 of the browsing screen 160displays the price information 161 of the end user price 161 a only andthe license description information 163. When the user is a lowerintermediary dealer who does not have an ordering right, the description166 of the browsing screen 160 displays the end user price 161 a as wellas the lower intermediary dealer price corresponding to user level 2(ch2).

<Ordering Processing Unit 112>

The ordering processing unit 112 has functions corresponding to adistribution authorization notification unit, an ordering screen outputunit, and an application distribution information management unit. Theordering processing unit 112 outputs an ordering screen used forordering an application to the terminal 400 in response to a requestfrom a specialized dealer (an intermediary dealer) or an end user who isauthorized to placing an online order, received from the terminal 400,for example. Due to this, the ordering processing unit 112 checks anordering right of the user ID included in the received ordering requestby referring to the user storage unit 122. The ordering processing unit112 provides the ordering screen only when the user has the orderingright. Here, an ordering process may be executed by the terminal 400 ofthe higher intermediary dealer (user level 3) only, for example. Forexample, the ordering processing unit 112 may display a menu screendisplayed when a user logs in so that, on the basis of the ID of thelogged-in user, only the user who is a higher intermediary dealer, canselect ordering. Upon receiving an ordering screen request, the orderingprocessing unit 112 may determine whether a subsequent process is to beperformed on the basis of the user ID. As described above, as for a userhaving an ordering right, an ordering button or the like may bedisplayed on the browsing screen 160 so that the user can place anorder.

Upon receiving, from the terminal 400, an application purchase request(that is, an edge server ID of the edge server 200 serving as adistribution destination of the application and a license requestcorresponding to the number of client target edge devices 300) from auser having an ordering right, the ordering processing unit 112transmits the serial number (a license key) of the applicationcorresponding to the purchase request to the terminal 400. Here, theserial number (a license key) is information for identifying anapplication to be distributed and indicating that distribution of theapplication is authorized. More specifically, the ordering processingunit 112 generates a serial number (a license key) of an applicationcorresponding to the purchase request. The ordering processing unit 112stores ordering processing data including an application ID, an edgeserver ID of a distribution destination edge server 200, a serial number(a license key) in the distribution management storage unit 124. Theordering processing unit 112 transmits a serial number (a license key)to the terminal 400 of the higher intermediary dealer that hastransmitted the purchase request, for example. The serial number (alicense key) received from the sales management server system 100 isdisplayed on the terminal 400 of the higher intermediary dealer that hasexecuted this processing. By doing so, the application sales managementsystem 1000 can notify the higher intermediary dealer that hastransmitted the purchase request of the serial number (a license key)for distributing the purchased application.

A lower intermediary dealer or an end user who does not have an orderingright is not notified of the serial number (a license key) from theapplication sales management system 1000. Therefore, the applicationsales management system 1000 can prevent a lower intermediary dealer oran end user from downloading applications without paying for theapplications. In the present embodiment, although the serial number (alicense key) is described as an example of distribution authorizationinformation, the distribution authorization information is not limitedto the serial number (a license key).

It has been described that, when the ordering processing unit 112receives an application purchase request transmitted from the terminal400 of a user having an ordering right, the ordering processing unit 112transmits the serial number (a license key) of the applicationcorresponding to the purchase request to the terminal 400. However, amethod in which the serial number (a license key) of the application isnot transmitted immediately may be considered. For example, when theordering processing unit 112 receives, from the terminal 400, anapplication purchase request from the terminal 400 of the user having anordering right, the ordering processing unit 112 may transmit an emailincluding an ID and a password for logging in an exclusive screen (notillustrated) displaying the serial number (a license key) of anapplication, for example, to the user who has transmitted theapplication purchase request as information related to a distributionauthorization. When the user displays the exclusive screen and then logsin using the ID and the password described in the email, the orderingprocessing unit 112 displays the serial number (a license key) on theexclusive screen. The email may include a URL for displaying theexclusive screen in addition to the ID and the password. It is assumedthat the address of an email corresponding to a user is registered inthe storage unit 120. By doing so, for example, when a third partyfraudulently uses the terminal 400 of the user having an ordering right,the serial number is left unknown to the third party and the system canbe operated in a mechanism with improved security.

It has been described that the ordering processing unit 112 receives theapplication purchase request (that is, an edge server ID of the edgeserver 200 serving as a distribution destination of the application anda license request corresponding to the number of client target edgedevices 300) from the user having an ordering right from the terminal400. However, the application purchase request may not include a licenserequest corresponding to the number of client target edge devices 300.In this case, the control unit 110 of the sales management server system100 may designate a necessary license based on the number of clienttarget edge devices 300 by referring to the edge server informationstored in the storage unit 120 (the user storage unit 122) from the edgeserver ID.

<Distribution Processing Unit 113>

The distribution processing unit 113 has functions corresponding to anapplication distribution unit and an application distributioninformation management unit. Upon receiving an application distributionrequest together with the serial number (a license key) from theterminal 400, the distribution processing unit 113 specifies anapplication to be distributed and the distribution destination edgeserver 200 by referring to the distribution management storage unit 124on the basis of the serial number (the license key) and distributes theapplication to the distribution destination edge server 200. Morespecifically, the distribution processing unit 113 specifies the edgeserver 200 that distributes the application from the serial number (thelicense key) in response to an application distribution request from anend user or a specialized dealer (an intermediary dealer), received fromthe terminal 400. The distribution processing unit 113 distributes theapplication corresponding to the serial number (the license key) and thelicense to the specified edge server 200. Here, the license is useauthorization information on the edge device 300 serving as a client(that is, a connection and/or input/output target) of the application.The license may be distributed to the edge server 200 in a state ofbeing included in the application. The license may be distributed to theedge server 200 separately from the application.

By doing so, an end user or a lower intermediary dealer can download apurchased application to the specified edge server 200. In this manner,since the distribution processing unit 113 specifies the application andthe edge server 200 on the basis of the serial number (the license key)included in the distribution request, a specific user who knows theserial number only can transmit a distribution request. That is, evenwhen a third party transmits a distribution request, an application isnot distributed since the third party does not know the serial number.Since the serial number specifies the edge server 200 serving as theapplication distribution destination, even if a third party happens toknow the serial number, the application cannot be distributed to aserver other than the specified edge server 200.

<Mall Processing Unit 114>

The mall processing unit 114 has functions corresponding to a usersetting unit and an administrator setting unit. The mall processing unit114 performs processing on a mall. The mall processing unit 114 createsa mall on the basis of a creation request from the terminal 400 by aspecialized dealer such as a machine tool manufacturer, for example,sets a user who is authorized to access the mall, and stores informationon the mall in the mall storage unit 123.

[Generation of Mall]

The mall processing unit 114 generates a mall in correlation with anintermediary dealer ID on the basis of a creation request from theterminal 400 of a higher intermediary dealer by a specialized dealersuch as a machine tool manufacturer. As described above, a mall is avirtual store that includes an application group including one or moreapplications and can be created for each application group. By doing so,a specialized dealer (a higher intermediary dealer) such as a machinetool manufacturer can designate a user who is authorized to access theapplication group for each of the related application groups. Due tothis, a specialized dealer (a higher intermediary dealer) such as amachine tool manufacturer can segment users for each application groupand can promote sales effectively.

A developer of an application may set an authorization to generate amall and access the mall. Here, the developer is not limited to aspecialized dealer such as a machine tool manufacturer but may be an enduser such as an automobile company. Moreover, the developer may be aperson who carried out entrusted development (in-house development) onthe basis of a request from a specialized dealer such as a machine toolmanufacturer.

[User Authorized to Access Mall]

More specifically, the mall processing unit 114 correlates a mallcreated on the basis of a creation request from a specialized dealer (ahigher intermediary dealer) such as a machine tool manufacturer with auser ID authorized to access the mall. For example, the mall processingunit 114 may correlate the exclusive mall 173 with a user authorized toaccess the mall on the basis of an input from the terminal 400 of aspecialized dealer (a higher intermediary dealer) such as a machine toolmanufacturer using a mall setting screen or the like (not illustrated).For example, the terminal 400 of the higher intermediary dealer selectsa user registration to the exclusive mall 173, for example, from a menuscreen (not illustrated). By doing so, the mall processing unit 114 canadd a user ID of a user authorized to access to an exclusive mallcorrelated with a user ID indicating an administrator of the higherintermediary dealer.

As described above, by providing an application grouping function usinga mall, a specialized dealer (a higher intermediary dealer) such as amachine tool manufacturer can sell applications developed by itself orin development to end users who are customers thereof. Moreover, thespecialized dealer (a higher intermediary dealer) such as a machine toolmanufacturer manages the content of the exclusive mall 173 by itself.Due to this, it is possible to secure confidentiality such that users,even an operating company, other than a user who is authorized to accessa mall cannot access the exclusive application 172 correlated with themall (that is, cannot browse applications included in the mall).Moreover, a user who is authorized to access the mall can obtainapplication information more preferentially than other users who are notauthorized to access the mall. Due to this, a user who is authorized toaccess the mall can use data indicating the operation state related tothe edge device 300, data indicating the production state, dataindicating the quality state of a product, and data indicating theoperating state, for example, earlier than other users. For example, itis particularly effective for the user to obtain information onapplications in development earlier than other users.

<Contract Renewal Processing Unit 115>

The contract renewal processing unit 115 has a function corresponding toa contract renewal notification unit. The contract renewal processingunit 115 transmits a notification for renewing the contract of anapplication downloaded to the edge server 200 to a specialized dealer(an intermediary dealer) who is a purchaser of the application and/or anend user of a license destination of the application, for example, byreferring to the distribution management storage unit 124. The terminalnotified of by the contract renewal processing unit 115 may be theterminal 400 of a specialized dealer (an intermediary dealer) who is apurchaser of the application and/or the end user of a licensedestination of the application and may be another terminal (for example,a portable terminal) of a specialized dealer (an intermediary dealer)who is a purchaser of the application and/or the end user of a licensedestination of the application. As for a notification method, thenotification may be displayed on the menu screen and may be transmittedvia an email or the like, for example. More specifically, the contractrenewal processing unit 115 extracts an edge server ID and anapplication ID of the edge server 200 of which the next contract renewalnotification date has arrived and which is not notified of by anotification completion flag by referring to the distribution managementstorage unit 124 at predetermined timings (for example, once a week oronce a month). The contract renewal processing unit 115 notifies aspecialized dealer (an intermediary dealer) who is a purchaser of theapplication and/or an end user corresponding to the edge server ID ofthe edge server 200 of a license destination of the application of thefact that renewal of the contract of the application corresponding tothe application ID is necessary. Therefore, the contract renewalprocessing unit 115 can prevent omission of the contract renewal of theuser and cause the user to update the contract without forgetting.

The communication unit 130 is a communication control device thattransmits and receives data to and from an external device (for example,the edge server 200, the terminal 400, and the like) via the network N1.

Next, a configuration of the edge server 200 will be described. FIG. 7Ais a functional block diagram of the edge server 200 according to thepresent embodiment. The edge server 200 includes a control unit 210, astorage unit 220, and a communication unit 230. The control unit 210 isa CPU, for example, and controls the edge server 200 in an integratedmanner by executing various programs stored in the storage unit 220 andapplications downloaded from the sales management server system 100.

In the present embodiment, the control unit 210 includes a licensecontrol unit 211 as a functional unit based on an application stored inthe storage unit 220. The license control unit 211 controls connectionand/or input/output to an application and the edge device 300 on thebasis of a license related to the application.

More specifically, when an application stored in the application storageunit 221 is activated by the control unit 210, the license control unit211 reads a license corresponding to the application. The licensecontrol unit 211 specifies an edge device 300 which is authorized as aclient which is an input/output destination of the application on thebasis of the read license. More specifically, for example, the licensecontrol unit 211 determines whether the edge device 300 that requestsconnection to the application satisfies requirements defined in thelicense on the basis of the license. When the edge device 300 satisfiesthe requirements defined in the license, the license control unit 211authorizes the request for connection to the application and controlsinput/output to the application. When the edge device 300 does notsatisfy the requirements defined in the license (for example, exceedsthe license), the license control unit 211 rejects the request forconnection to the application and prohibits input/output to theapplication. By doing so, the license control unit 211 can controlconnection and/or input/output between the edge device 300 and theapplication distributed to the edge server 200 according to thedistributed license.

The storage unit 220 includes an application storage unit 221 thatstores applications to be executed by the control unit 210. Theapplication storage unit 221 stores applications distributed from thesales management server system 100 and licenses related to theapplications. The communication unit 230 is a communication controldevice that transmits and receives data to and from an external device(for example, the sales management server system 100 and the like) viathe network N1 and transmits and receives data to and from an externaldevice (the edge device 300) via the network N2.

[Modification]

Although it has been described that the edge server 200 storesapplications and licenses related to the applications in the applicationstorage unit 221, applications and licenses may be distributed from thesales management server system 100 and be stored separately. Next, aconfiguration of an edge server 200-2 that stores applications andlicenses separately will be described.

FIG. 7B is a functional block diagram of the edge server 200-2 accordingto a modification of the present embodiment. The edge server 200-2includes a control unit 210-2, a storage unit 220-2, and a communicationunit 230. The control unit 210-2 includes a license control unit 211-2as a functional unit based on the application stored in the storage unit220-2. The license control unit 211-2 controls connection and/orinput/output between the application and the edge device 300 on thebasis of the license related to the application stored in a licensestorage unit 222.

More specifically, when an application stored in the application storageunit 221-2 is activated by the control unit 210-2, the license controlunit 211-2 extracts a license corresponding to the application from thelicense storage unit 222. The license control unit 211-2 specifies theedge device 300 authorized as a client which is an input/outputdestination of the application on the basis of the extracted license,authorizes the request for connection to the application so as tosatisfy the requirements defined in the license, and controlsinput/output to the application. By doing so, the license control unit211-2 can control connection and/or input/output between the edge device300 and the application distributed to the edge server 200 according tothe distributed license.

The storage unit 220-2 includes an application storage unit 221-2 thatstores an application to be executed by the control unit 210-2 and thelicense storage unit 222. The application storage unit 221-2 stores anapplication distributed from the sales management server system 100. Thelicense storage unit 222 stores a license related to the applicationdistributed simultaneously with the application from the salesmanagement server system 100.

Hereinabove, the functional blocks included in the sales managementserver system 100 and the edge server 200 have been described. Therespective devices included in the application sales management system1000 can be realized by hardware, software, or a combination thereof.Here, a device being realized by software means that a computer readsand executes a program (an application) whereby the device is realized.As a specific example, the sales management server system 100 and theedge server 200 can be realized by incorporating a program (anapplication) for realizing the present embodiment in an ordinary server.

Next, the flow of a process of purchasing an application using theapplication sales management system 1000 on the basis of a conventionalbusiness practice will be described on the basis of FIG. 8. FIG. 8 is adiagram illustrating an overview of the flow of an applicationpurchasing process including the process of the application salesmanagement system 1000 according to the present embodiment. In thefollowing description, a case in which an end user, a lower intermediarydealer, and a higher intermediary dealer purchase an applicationdistributed to the edge server 200 of the end user using the applicationsales management system 1000 will be described as an example. In thisexample, unless particularly stated otherwise, a case in which threelevels including an end user (user level 1), a lower intermediary dealer(user level 2) such as a system integrator, and a higher intermediarydealer (user level 3) such as a machine tool manufacturer are set as theuser level will be described. However, two or more lower intermediarydealers and two or more higher intermediary dealers may be provided, andone intermediary dealer including a lower intermediary dealer and ahigher intermediary dealer may be provided. Unless particularly statedotherwise, although the ordering right is set to the higher intermediarydealer (user level 3), the ordering right may be set to the lowerintermediary dealer (user level 2) and/or the end user (user level 1).

In step S1 (hereinafter step S will be referred to simply as “S”) inFIG. 8, each user (an end user and an intermediary dealer) browseapplications. In S2, when a user purchases an application, the userorders the application. In S3, the user acquires a serial number of theapplication on condition that the user pays for the cost for purchasingthe application, for example. In S4, the user distributes theapplication to the edge server 200 using the serial number.

Next, the relationship between each user and the application salesmanagement system 1000 in each step will be described. FIG. 9 is adiagram for describing how applications are browsed using the salesmanagement server system 100 according to the present embodiment. FIG.10 is a diagram for describing how applications are ordered using thesales management server system 100 according to the present embodiment.FIG. 11 is a diagram for describing how applications are distributedusing the sales management server system 100 according to the presentembodiment.

(1) Browsing of Applications

In correspondence to S1 in FIG. 8, as illustrated in FIG. 9, whenpurchasing applications, an end user, a lower intermediary dealer, and ahigher intermediary dealer access the sales management server system 100from the respective terminals 400 to transmit an application informationbrowse request.

The end user browses application information output from the terminal400 as a response to the browse request. After browsing the applicationinformation, the end user determines an application to be purchased onthe basis of a configuration of the edge device 300 provided in a plantfacility thereof, the price information of the application, and thelike. After that, the end user asks for an estimation to a lowerintermediary dealer who is in direct transaction with the end useraccording to a conventional business practice. The end user may ask forcompetitive bids to a plurality of lower intermediary dealers. Theestimation is not the target of processing of the application salesmanagement system 1000.

The end user receives an estimate sheet from the lower intermediarydealer. The end user determines an application to be purchased.

The lower intermediary dealer browses the application information outputto the terminal 400 as a response to the browse request in response toan estimation request from the end user or in order to find anapplication useful for the end user. Moreover, the lower intermediarydealer receives an estimation request from the end user and asks for anestimation to a higher intermediary dealer who is in direct transaction.The lower intermediary dealer receives an estimate from the higherintermediary dealer. The lower intermediary dealer creates an estimatefor the end user and provides an estimate sheet to the end user.Furthermore, the lower intermediary dealer may provide information on anapplication useful for the end user to the end user.

The higher intermediary dealer browses the application informationoutput to the terminal 400 as a response to the browse request inresponse to the estimation request from the lower intermediary dealer orin order to find an application useful for the lower intermediarydealer. Moreover, the higher intermediary dealer receives an estimationrequest from the lower intermediary dealer, creates an estimate sheetfor the lower intermediary dealer, and provides the estimate sheet tothe lower intermediary dealer. Furthermore, the higher intermediarydealer may provide information on an application useful for the lowerintermediary dealer to the lower intermediary dealer.

(2) Ordering of Applications

In correspondence to S2 in FIG. 8, the end user places an order for anapplication to the lower intermediary dealer when the end user hasdecided to purchase an application according to the received estimatesheet. The lower intermediary dealer receives an ordering request fromthe end user and places an order for an application to the higherintermediary dealer. In this case, the ordering source user transmits anapplication to be ordered and an edge server ID of the edge server 200that downloads the application to an ordering destination. Here, theedge server ID is identification information for identifying the edgeserver 200. The ordering request is not the target of processing of theapplication sales management system 1000.

As illustrated in FIG. 10, a higher intermediary dealer having anordering right accesses the sales management server system 100 from theterminal 400, designates an edge server ID, and places an order for theapplication. When an order is placed, the sales management server system100 transmits the serial number of the ordered application to theterminal 400 of the higher intermediary dealer. Here, the salesmanagement server system 100 may transmit the serial number of theordered application directly to the terminal 400 of the higherintermediary dealer as a response to the ordering process. This isbecause the higher intermediary dealer who is the user who can place anorder using the application sales management system 1000 is a companywhose credit is trusted by an operating company.

When an order is placed, the sales management server system 100 maytransmit an email including an ID and a password for logging in anexclusive screen (not illustrated) for displaying the serial number ofan application, for example, on another terminal (or the terminal 400)of the higher intermediary dealer to the higher intermediary dealer. Inthis manner, the serial number of the ordered application may not beinformed of directly by the higher intermediary dealer as a response tothe ordering process. When a user logs in from the exclusive screenusing the ID and the password included in the email, the salesmanagement server system 100 displays the serial number on the exclusivescreen. The email may include a URL for displaying the exclusive screenin addition to the ID and the password for logging in the exclusivescreen.

(3) Paying for Applications

In correspondence to S3 in FIG. 8, the higher intermediary dealer havingreceived the serial number is paid for the application from the lowerintermediary dealer and notifies the lower intermediary dealer of theserial number. Similarly, the lower intermediary dealer is paid for theapplication from the end user and notifies the end user of the serialnumber. Here, providing of the serial number from the higherintermediary dealer to the lower intermediary dealer and providing ofthe serial number from the lower intermediary dealer to the end user maybe realized using an arbitrary means and may be realized appropriatelyusing a facsimile, an email, a document, and the like, for example.Payment for the application by the lower intermediary dealer or the enduser and the subsequent acquisition of the serial number related to theapplication are based on an existing technique and are not the target ofthe processing of the application sales management system 1000.

(4) Distribution of Applications

In correspondence to S4 in FIG. 8, as illustrated in FIG. 11, the enduser being notified of the serial number or the lower intermediarydealer having been paid from the end user transmits a distributionrequest including the serial number to the sales management serversystem 100 from the terminal 400. When a distribution request istransmitted, the sales management server system 100 distributes anapplication corresponding to the serial number to the edge server 200.The edge server 200 stores the distributed application in theapplication storage unit 221.

Next, a process flow of the sales management server system 100 in therespective steps will be described. First, the flow of an applicationbrowsing process will be described. FIG. 12 is a flowchart illustratinga browsing information providing process of the sales management serversystem 100 according to the present embodiment.

In order to browse the application information, each user operates theterminal 400 to log in the sales management server system 100. Here,login is performed using an existing method, and user authentication isperformed using such as a password management file including personalinformation of a user, an ID, a password, and the like, for example, toascertain that the user is an authorized user. The user selects browsingof applications from the menu screen (not illustrated) displayed on theterminal 400. In S10, the browsing information providing unit 111 of thesales management server system 100 receives a browse request transmittedby the terminal 400. In S11, the browsing information providing unit 111checks the user level of the user ID included in the received browserequest by referring to the user storage unit 122. In S12, the browsinginformation providing unit 111 specifies a mall ID in which the receiveduser ID is included in an authorized user ID or an administrator ID byreferring to the mall storage unit 123.

In S13, the browsing information providing unit 111 extracts anapplication including the mall ID specified in S12 by referring to theapplication storage unit 121. The browsing information providing unit111 extracts an application in which the mall ID is blank by referringto the application storage unit 121. In S14, the browsing informationproviding unit 111 extracts information on the extracted applicationfrom the application storage unit 121 and generates the browsing screen160. In this case, the browsing information providing unit 111 extractsthe price information corresponding to the user level ascertained in S11from the application storage unit 121. In S15, the browsing informationproviding unit 111 transmits the generated browsing screen 160 to theterminal 400 that has transmitted the browse request. After that, thesales management server system 100 ends this process.

Next, the flow of an application ordering process will be described.FIG. 13A is a flowchart illustrating the ordering process of the salesmanagement server system 100 according to the present embodiment. InFIG. 13A, a serial number is transmitted directly in response to anordering request. In order to place an order for an application to bepurchased, for example, a higher intermediary dealer having an orderingright operates the terminal 400 and selects ordering of an applicationfrom the menu screen (not illustrated) displayed on the terminal 400. InS20, the ordering processing unit 112 of the sales management serversystem 100 receives an ordering screen request transmitted by theterminal 400.

In S21, the ordering processing unit 112 transmits an ordering screen tothe terminal 400 that has transmitted the request. The ordering screenmay be similar to the browsing screen 160 illustrated in FIG. 6, forexample. Here, when the control unit 110 of the sales management serversystem 100 designates a necessary license based on the number of clienttarget edge devices 300 by referring to the edge server informationstored in the storage unit 120 (the user storage unit 122) from the edgeserver ID, information on the number of licenses corresponding to thenumber of client target edge devices 300 is not displayed. The terminal400 inputs information for ordering by referring to the ordering screen.The terminal 400 transmits a purchase request by selecting a button forplacing an order included in the ordering screen, for example. By doingso, in S22, the ordering processing unit 112 receives a purchase requestfrom the terminal 400.

In S23, the ordering processing unit 112 generates a serial number of anapplication corresponding to the purchase request. The orderingprocessing unit 112 stores data corresponding to respective itemsincluding the serial number in the distribution management storage unit124. In S24, the ordering processing unit 112 transmits the serialnumber to the terminal 400 of the higher intermediary dealer who hastransmitted the purchase request. After that, the ordering processingunit 112 ends this process.

[Modification]

In the above-described flowchart, although the serial number istransmitted directly in response to an ordering request, an ID and apassword for logging in the exclusive screen for displaying the serialnumber may be transmitted. FIG. 13B is a flowchart illustrating anordering process of the sales management server system 100 according toa modification of the present embodiment. S20 to S23 are similar to S20to S23 of the flowchart in FIG. 13A. In S24 a, the ordering processingunit 112 generates an ID and a password for logging in the exclusivescreen. In S25 a, the ordering processing unit 112 generates an emailincluding the generated ID and password and transmits the email. When auser having received the email logs in the exclusive screen using the IDand the password included in the email, a serial number is displayed.Therefore, the user can know the serial number corresponding to thepurchase request.

Next, the flow of an application distribution process will be described.FIG. 14 is a flowchart illustrating an application distribution processof the sales management server system 100 according to the presentembodiment. In order to transmit an application distribution request,for example, an end user operates the terminal 400, selects distributionof applications, for example, from the menu screen (not illustrated)displayed on the terminal 400, inputs a serial number of an applicationto be distributed to the edge server 200 on a distribution screen (notillustrated) changed from the menu screen, and transmits a distributionrequest to the sales management server system 100.

In S30, the distribution processing unit 113 of the sales managementserver system 100 receives the distribution request from the terminal400. Here, an end user may transmit the distribution request using theterminal 400 of the end user, or the lower intermediary dealer maytransmit the distribution request using the terminal 400 of the lowerintermediary dealer. S31, the distribution processing unit 113 specifiesan application and the edge server 200 to which the application isdistributed by referring to the distribution management storage unit 124on the basis of the serial number included in the distribution request.

In S32, the distribution processing unit 113 distributes the specifiedapplication to the specified edge server 200. In this case, thedistribution processing unit 113 sets a next contract renewalnotification date on the basis of the calculated next contract renewaldate and at an appropriate date (for example, one month before anexpiration date). When an application is sold out (that is, when renewalof a contract is not necessary), the next contract renewal notificationdate is left blank. In S33, the distribution processing unit 113transmits a notification of completion of distribution to the terminal400 that has transmitted the distribution request when distribution ofan application to the edge server 200 is completed. After that, thedistribution processing unit 113 ends this process.

Next, the flow of an application renewal process will be described. FIG.15 is a flowchart illustrating a contract renewal notification processof the sales management server system 100 according to the presentembodiment. The sales management server system 100 executes the contractrenewal notification process at predetermined timings (for example, oncea week or once a month). In S40, the contract renewal processing unit115 of the sales management server system 100 extracts an edge server IDand an application ID of which the next contract renewal notificationdate has arrived and which is not notified of by a notificationcompletion flag by referring to the distribution management storage unit124.

In S41, the contract renewal processing unit 115 notifies a user (anapplication purchaser and an application user) corresponding to the edgeserver ID of a fact that renewal of the contract of an applicationcorresponding to the application ID is necessary using a notificationdestination address. After that, the contract renewal processing unit115 ends this process.

Next, a process flow in the edge server 200 in which a downloadedapplication is activated will be described. FIG. 16 is a flowchartillustrating a license control process of the edge server 200 accordingto the present embodiment. FIGS. 17A and 17B are diagrams illustrating aspecific example of the edge device 300 of which the license iscontrolled by the edge server 200 according to the present embodiment.

In S50 in FIG. 16, the control unit 210 of the edge server 200 activatesan application stored in the application storage unit 221. Activation ofthe application is performed at the start-up of a server when the edgeserver 200 is turned on, for example. In S51, the license control unit211 reads the license 250 (licenses 250 a and 250 b) corresponding tothe application. In the example illustrated in FIG. 17A, the license 250a of application X designates an authorized edge device 300.Specifically, the authorized edge device 300 includes “EG1”, “EG2”, and“EG3” and can be managed by an edge device ID for identifying each edgedevice 300, for example. In the example illustrated in FIG. 17B, thelicense 250 b of application Y does not designate an authorized edgedevice 300 but indicates that “up to two devices can be connectedconcurrently”.

In S52, the license control unit 211 designates an authorized edgedevice 300 on the basis of the read license 250. In the exampleillustrated in FIG. 17B, up to two edge devices 300 are designated asthe edge device 300 which can establish connection to application Y. Forexample, when the edge devices 300 which have first establishedconnection are “EG1” and “EG3”, the license control unit 211 allows thetwo edge devices 300 to transmit data using application Y.

In S53, the license control unit 211 determines whether the edge device300 corresponding to the received data is a designated device. In thecase of FIG. 17A, if the edge device 300 having transmitted the receiveddata is any one of “EG1”, “EG2”, and “EG3”, the edge device 300 is adesignated device, whereas if the edge device 300 corresponding to thereceived data is “EG4” or “EG5”, the edge device 300 is not a designateddevice. Moreover, in the case of FIG. 17B, if the edge device 300corresponding to the received data is “EG1” or “EG3”, the edge device300 is a designated device (up to two concurrently connected devices),whereas if the edge device 300 corresponding to the received data is anyone of “EG2”, “EG4”, and “EG5”, the edge device 300 is not a designateddevice (up to two concurrently connected devices). If the device is adesignated device (S53: YES), the license control unit 211 proceeds toS54. On the other hand, if the device is not a designated device (S53:NO), the license control unit 211 proceeds to S55. In S54, the controlunit 210 performs processing of applications using the received data.

In S55, the control unit 210 determines whether an applicationtermination command has been received. The control unit 210 determinesthat an application termination command has been received when anoperation of turning off the edge server 200 is received or an operationof forcibly terminating the application is received, for example. Whenan application termination command is received (S55: YES), the controlunit 210 terminates the application. On the other hand, when anapplication termination command is not received (S55: NO), the licensecontrol unit 211 proceeds to S52. In the case of FIG. 17B, when theconnection of the edge device 300 of “EG3” is cut and then, theconnection of the edge device 300 of “EG2” is established, the licensecontrol unit 211 allows the two edge devices 300 of “EG1” and “EG2” totransmit data using application Y in S52. The methods of FIGS. 17A and17B may be combined, and the largest number of edge devices 300 may bedefined in the license, and the authorized edge device 300 may bedesignated within this range.

[Modification]

Next, the process in the edge server 200-2 in which a downloadedapplication operates will be described. FIG. 17C is a diagramillustrating a specific example of the edge device 300 of which thelicense is controlled by the edge server 200-2 according to amodification of the present embodiment. The process flow of the exampleillustrated in FIG. 17C is similar to that of FIG. 16 except for thefollowings. In the example illustrated in FIG. 17C, in the processcorresponding to S51 in FIG. 16, the license control unit 211-2 extractsa license corresponding to an application from the license storage unit222. In the example illustrated in FIG. 17C, the license of the licensestorage unit 222 of application Z does not designates an authorized edgedevice 300 but indicates that “up to two devices can be connectedconcurrently”. Therefore, in the process corresponding to S52 in FIG.16, the license control unit 211-2 sets the number of edge devices 300which can establish connection to application Z to two on the basis ofthe extracted license. The methods of FIGS. 17A and 17C may be combined,the largest number of edge devices 300 may be defined in the license,and the authorized edge device 300 may be designated within this range.

In this way, the application sales management system 1000 can purchaseand download an application to be operated in the edge server 200 fromthe sales management server system 100. In this case, since the salesmanagement server system 100 control the executability of a processrelated to purchase of applications and the like on the basis of theuser level and an ordering right of a user, it is possible to facilitatethe purchase of applications using the application sales managementsystem 1000 while making use of a conventional business practice.

The programs as well as the applications used in the present inventionmay be stored using various types of non-transitory computer readablemedia and be supplied to a computer. The non-transitory computerreadable media include various types of tangible storage media. Examplesof the non-transitory computer readable media include a magneticrecording medium (for example, a flexible disk, magnetic tape, or a harddisk drive), a magneto-optical recording medium (for example, amagneto-optical disk), a CD read only memory (CD-ROM), a CD-R, a CD-R/W,and a semiconductor memory (for example, a mask ROM, a programmable ROM(PROM), an erasable PROM (EPROM), a flash ROM, or a random access memory(RAM)). Moreover, the programs may be supplied to a computer in a formof various types of transitory computer readable media. Examples oftransitory computer readable media include electrical signals, opticalsignals, and electromagnetic waves. The transitory computer readablemedia can supply programs to a computer via a wired communication pathsuch as an electric wire and an optical fiber or a wirelesscommunication path.

The above-described embodiment is a preferred embodiment of the presentinvention. However, the scope of the present invention is not limited tothe embodiment only but the present invention can be embodied in variousmodifications without departing from the spirit of the presentinvention.

(Modification 1)

In the above-described embodiment, the number of edge devices 300authorized as a client which is an input/output destination of anapplication distributed to the edge server 200 is the number of edgedevices 300 communicably connected to the edge server 200, set by thelicense. However, the present invention is not limited thereto. Forexample, when a plurality of edge devices 300 is connected to the edgeserver 200 via a controller, the use of the plurality of edge devices300 connected to the controller may be authorized using the controlleras one license, and each of the plurality of edge devices 300 connectedto the controller may be authorized as the controller as one license.Such control may be designated for respective applications.

(Modification 2)

In the above-described embodiment, a user is correlated with a userlevel and the price information displayed to a user is controlledaccording to the user level. Moreover, an ordering right is set inadvance to a user and an ordering process is controlled. However, thepresent invention is not limited thereto. For example, users who canpurchase applications may be managed by a purchaser management unit, andduring execution of an ordering process, when a user is determined to beauthorized to place an order on the basis of the purchaser managementunit, ordering of applications may be authorized. Moreover, thepurchaser management unit may manage password information (specificpassword information) known to a user only, and a comparing unit thatcompares password information received by a receiving unit when a userplaces an order with the password information managed by the purchasermanagement unit may be provided so that ordering of applications isauthorized when both pieces of password information match to therebyprevent fraud of other persons.

(Modification 3)

In the embodiment based on the conventional business practice, the userlevel is classified into three levels (an end user, a lower intermediarydealer, and a higher intermediary dealer), and a person capable ofperforming an application ordering process (that is, a person having anordering right) is the higher intermediary dealer only. However, thepresent invention is not limited thereto. For example, the orderingright may be set for respective users on the basis of the creditabilityof individual users regardless of the user level. Moreover, the orderingright may be set to all higher intermediary dealers, and the orderingright may be set to the end user and the lower intermediary dealer onthe basis of the creditability or the like of the individual users.Similarly, the ordering right may be set to all higher intermediarydealers and all lower intermediary dealers, and the ordering right maybe set to an end user on the basis of the creditability or the like ofindividual users. Moreover, since a user ID for accessing theapplication sales management system 1000 is assigned to users whosatisfy predetermined requirements (qualifications or the like), theordering right may be set to all users assigned with user IDs. In anycase, an end user transmits an application ordering request to anintermediary dealer such as a system integrator, for example, so thatthe end user does not place an order directly to the sales managementserver system 100. By doing so, the end user can ask an intermediarydealer such as a system integrator to set environments of hardware andsoftware when using applications.

(Modification 4)

In the embodiment described above, the user level is classified intothree levels (an end user, a lower intermediary dealer, and a higherintermediary dealer). However, the present invention is not limitedthereto. The user level may be classified into two levels or four ormore levels according to a business practice.

(Modification 5)

In the embodiment described above, a serial number (a license key) isused as distribution authorization information. However, the presentinvention is not limited thereto. The distribution authorizationinformation may be information for authorizing distribution ofapplications.

(Modification 6)

In the embodiment described above, various pieces of information arestored in the storage unit 120 of the sales management server system100. The pieces of information stored in the storage unit are examplesonly, and other pieces of information may be included. Moreover, a dataretention method is an example only.
